Both the 900MHz and the 2.4GHz ISM bands are approved as unlicensed
spectrums subject to certification by device.
As a general guideline, consider integrating 2.4GHz modules if
your application requires high data throughput or worldwide deployment.
AC5124 and AC4424
modules simplify the RF design effort and assure successful field
operation around the globe. Consider integrating 900MHz modules
if your application is cost-sensitive, handheld, or requires long
range. AC4790 and AC4490
low cost, long range transceivers can replace miles of cable in
harsh industrial areas.
